Steelers release linebacker Harrison

PITTSBURGH — James Harrison’s snarling tenacity made the Pittsburgh Steelers linebacker one of the NFL’s most intimidating players for nearly a decade.

Big hits — some legal, some not so much — also turned the outspoken five-time Pro Bowler into focal point for a league-wide crackdown on helmet-to-helmet contact.

Harrison’s outlaw image made him beloved in Pittsburgh but reviled elsewhere. His onerous contract, however, no longer worked for a team with serious salary cap issues. The Steelers released the former Defensive Player of the Year on Saturday when the two sides could not agree on a more cap-friendly deal.

“It’s been a great run but all good things must come to a end,” Harrison posted on his Twitter account Saturday afternoon. “Thank you Steelers Nation I will miss you all!”

Pittsburgh general manager Kevin Colbert and Harrison’s agent Bill Parise had spent the last few days trying to iron out a new deal but couldn’t reach any common ground. Harrison was entering the final two years of a $51-million extension he signed in 2009 and was scheduled to make $6.57 million in 2013.

Instead, Harrison — who turns 35 in May — will find himself looking for work for the first time since he became a fixture on the Pittsburgh’s defense since 2006.

“James has been an integral part of our success during his years in Pittsburgh and has helped us win two Lombardi trophies during that time,” Colbert said in a statement. “We appreciate all of his efforts and wish him the best.”

Harrison is the first cap move by the Steelers this offseason as they try to get under the $123 million salary cap by Tuesday.
